74FCT162244ETPAG

Overview

The IDT74FCT162244ETPAG is a high-speed, low-power CMOS bus driver belonging to the 74FCT logic series. It features four independent non-inverting drivers, each handling four bits for a total of 16 channels. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 48-pin TSSOP surface-mount package. It provides balanced output drivers with ±24mA current capability and includes power-off disable functionality to support live insertion applications.

Feature Summary

• Four independent 4-bit non-inverting bus drivers
• Power-off disable outputs permit live insertion
• Balanced output drivers reduce system switching noise
• High ESD protection exceeding 2000V per MIL-STD-883

Applications

• Memory address latching
• I/O port buffering
• Bus driver implementations
• Clock distribution networks

Procurement Notes

Verify the specific suffix 'ETPA' or 'ETPAG' against official Renesas/IDT documentation to confirm pinout compatibility and RoHS status. Confirm that the manufacturer has not issued a Product Change Notification (PCN) affecting the package or material composition prior to procurement.

Selection Notes

Select this component when a 16-channel buffer with high drive strength and live insertion capability is required. Ensure the design supports the 4.5V to 5.5V operating range. Verify that the 48-pin TSSOP footprint matches the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the IDT 74FCT family, designed as a high-speed replacement for older ABT logic functions. It is manufactured using 0.5 micron CMOS technology to achieve low power consumption while maintaining fast propagation delays suitable for modern digital systems.

Replacement Considerations

Public confirmed substitute part numbers include CY74FCT162244CTPVC from Texas Instruments.
